The bloodletters and the herald are attached to each other and are the counter-assault.

The herald of Tzeentch does what he wants. I was going to give him bolt, but I don't need to include any anti-tank, so I went for Breath. I was thinking about removing We Are legion, but if I kill a unit outright, WaL will still help with re-directing my fire to another unit. Thoughts?

The pink horrors are mostly a deathstar. I will deepstrike them a bit far away so the enemy cannot tie them up in combat, passively saving his skin from being wrecked by the IG heavy support cannons.

The demon prince is for the epic pavane that will synergize so awesomely with the battle cannons. >:D

the flamers are the suicide unit, obviously.

I will also hide the khorne units behind the tanks. They will deepstrike somewhere safe!

as will the demon prince...

If you think anything needs changing, or if I should toss in some bolts for good measure, let me know.

I say it looks perfect from IG side except personally i would be going for gunline in the troop and hq section simply because you gonna be all up in his face and getting objectives, he can just sit back and pop a few caps in em.

Thats purely personally choice though i'm sure his will do fine

For those enemies who willingly move against the Supreme judgement, of the Divine Emperor of man kind, Eternal death shall be granted. Amen
